The European Prospective Investigation into Cancer and Nutrition in Norfolk is a population based prospective study of approximately 25,000 men and women resident in Norfolk United Kingdom. They were aged 39-79 years when first recruited from general practice age sex registers at baseline assessment 1993-1997. While part of a ten country half million participant European collaboration originally aimed to investigate diet and other lifestyle determinants of cancer, the objectives of the Norfolk cohort from inception were expanded to encompass the trajectory of health, ill health and mortality in a population over time and to examine the biological and lifestyle determinants of health and chronic disease. Detailed data on sociodemographic, lifestyle, medical and family history were collected and a biological sample bank including urine and blood samples established. Participants have been followed up through repeat examinations, mailed questionnaires as well as through record linkage with routine health records including death certification by cause, cancer registration and hospital admissions by cause till present.
